Fix compilation errors and prepare for App Store submission

- Fix NotificationService warnings by replacing unused error parameters with _
- Add public domain header to NotificationService.swift
- Fix BluetoothMeshService compilation errors:
  - Replace removeAll with filter for processedKeyExchanges cleanup
  - Remove duplicate cleanupStalePeers function declaration
  - Remove duplicate peerLastSeenTimestamps property declaration
- All code now compiles cleanly for both iOS and macOS targets
